Installation Instructions (Sedan, with stub shaft removal)
This procedure outlines the process of installing rear disc brakes from a Nissan
200sx (82-83) or Maxima (86-87) on a 68-73 Datsun 510.
Note: There are two ways to remove your old drum brakes. The main problem is
removing the drum brake backing plate. They do not fit around the stub axles, so either
the plate has to be cut apart, or the stub axles removed. If you cut off the backing plate
ignore the steps below that do not pertain to you.
If you are going to pull out the stub axles, then you should replace the bearings and
seals.
1) Jack up the rear of your car and safely
support it on jack stands. Remove the
rear wheels. Disconnect the half-shafts
at the outer U-joints. Remove the brake
drums and the brake shoes.
3) Press out the stub axles, be careful
not to damage the threads during this
process.
2) These next steps are easiest
performed if the rear swing arms are
removed from the car. Use a die grinder
with a cutoff wheel to cut away the
smashed-in sides of the stub axle
locknuts. Use an impact gun to remove
the nut.
4) With the stub axles removed you can
now unbolt the drum backing plate.
5) Press out the old bearings and seals and press in new ones. These particular
bearings are common industrial application bearings that can be found at any
bearing supplier. The common part number is 6206. Buying from a bearing supplier
can save you considerable money. Don’t forget to re-install the spacer tube
between the bearings.
6) Clean all of the components
and reinstall the stub shafts and
the locknut. Be sure to use a
new locknut (Nissan p/n 4326221000). Follow the instructions
in the factory service manual
for proper installation
procedure.
7) Place the brake caliper mounting
bracket on the swing arm with the
orientation shown below. Make sure that
the open part of the “C” faces forward.
Use the included bolts to fasten it to the
swing arm. Torque bolts to 35 FT-LB. It
is recommended to use some blue
Loctite on these fasteners.
8) Install the brake rotor and hold it in
place with one lugnut.
9) Install the loaded caliper over the
rotor. Each caliper has an “R” or “L”
designation on it, make sure they get
installed on the correct sides.
11) Install your brake lines and bleed the
hydraulic system and check for leaks.
10) Use the included bolts to attach the
calipers to the brackets. Torque these
bolts to 35 FT-LB.
It is the buyers responsibility to ensure brackets and the corresponding
braking system is installed correctly. Any failure to do so could result in
rear brake failure and possibly injury. Seller assumes no responsibility for
product installation and use.
